The United Kingdom’s state-run National Health Service (NHS) has begun with the biggest-ever blood test trial to detect over 50 types of cancer, long before the appearance of symptoms. Grail Inc's flagship Galleri blood test is available in the US. The test can spot cancers that are not routinely screened for and also where they lie in the body.
This particular test will reportedly aid in looking at the DNA in a patient's blood in order to decide how to adjust or regulate cancer cells, should any occur. As per The Independent, survival rates increase if the diagnosis happens early. “We need to study the Galleri test carefully to find out whether it can significantly reduce the number of cancers diagnosed at a late stage. The test could be a game-changer for early cancer detection and we are excited to be leading this important research,” said Peter Sasieni, professor of cancer prevention at King's College London.
The NHS, meanwhile, announced that they will be recruiting some 1,40,000 volunteers in England to see how the test does. According to the NHS, blood samples of half of those volunteers will be tested and screened with the Galleri test immediately after.
Lung cancer accounts for the most common cause of death in the United Kingdom, among other cancer diseases, which accounts for nearly a fifth of total cancer deaths in the country. However, other cancers like breast, prostate, and bowel make up for 45% of the United Kingdom's deaths.
Starting today, blood samples will be collected from different mobile testing clinics in the United Kingdom, as a part of the NHS trial. This will be for people between 50 and 77 years of age.
Also, individuals from Greater Manchester, East of England, the North East, East Midlands, Cheshire and Merseyside, West Midlands, Kent and Medway, and South East London have been invited to take part.
